Evolvotron is an interactive "generative art" application to evolve images/textures/patterns through an iterative process of random mutation and user-selection driven evolution. If you like lava lamps, and never got tired of the Mandelbrot set, this could be the software for you. It's implemented using Qt, and is multithreaded.

EncFS is an encrypted pass-through filesystem
which runs in userspace on Linux (using the FUSE
kernel module). Similar in design to CFS and other
pass-through filesystems, all data is encrypted
and stored in the underlying filesystem. Unlike
loopback filesystems, there is no predetermined or
pre-allocated filesystem size.

peekabot is a versatile 3D visualization tool
targeted at robotics researchers and developers.
It's multi-platform, general purpose, easily
extendable, scalable, and does not depend on any
other frameworks to function. It also provides
some functionality for interacting with your
robots using the GUI. You can test your algorithms
in both simulated and real environments. The only
requirement is that the device can use TCP/IP.

Boost Extras is a set of extraneous libraries for
the Boost environment. It includes an adaptation
of the Boost source to compile with the GNU build
system, a set of classes to handle INI files, and
a class to derive from to use the
boost::intrusive_ptr&lt;&gt;.

libmagdev is a C library and command line utility to compute a prediction of the magnetic deviation (a.k.a. magnetic declination) at any location. It uses IGRF, a mathematical model of the earth's magnetic field.

Fing is a command line tool for network and service discovery. It provides you a complete view of any network in a very short time. Its smart discovery automatically detects the network type and uses the best technique to scan it. The best results are achieved on Ethernet networks (including Wireless ones), where Fing is able to detect all network hosts, firewalled ones included. The service discovery feature quickly detects active TCP services on a target host or network. Fing is based on Look@LAN.
